EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 278,830, dated June 5, 1883.

Application filed April 8, 1881. (No model.)

To all whom it may concern:

Be it known thatI, ROBERT WV. TAVENER, of WVest Bay City, Bay county, Michigan, have invented an Improvement in Extension-Tables, of which the following is a specification.

The nature of this invention relates to cer tain new and useful improvements in the construction of extension-tables; and the inven tion consists in the peculiar construction, arrangement, and various combinations of the parts, all as more fully hereinafter set forth.

Figure 1 'is a partial sectional side elevation, showing the table extended and in dotted lines as closed. Fig. 2 is a plan from the bottom, partly in section. Fig. 3 is a section 011 line In the accompanying drawings, which form a part of this specification, A 'Arepresent the two end portions of the table, mounted upon the legs B and connected together by the slides 0, each end of the table being provided with a suitable fall-leaf, D, the center leg, E, being secured to the frame F, which supports and is attached to the slide, all being constructed substantially in the ordinary manner.

G represents the main portion of the extension-top, which may be formed of narrow strips of wood a, these strips being secured to the top of the leg-frame F.

H represents the adjustable ends of the top G, and are formed of strips of wood a, secured close together by rivets or screws to a flexible apron, I.

J represents scrolls or chambers secured to the end portions, A, of the table at each corner, said scrolls being hidden from view by the side pieces, K, to which they are secured.

' These scrolls are situated so that the outer ends of the flexible portions H of the top extend into them at each corner, as shown, Fig. 1.

In practice, the table being extended and it is desired to shorten the same, the end portions, A, are advanced toward each other, which'necessarily causes the flexible sections of the top to travel into their respective scrolls until the 5 side bars, L, of the main frame come together. By this construction I am able to build an ex tension-table in which the use of separate leaves is dispensed with, and whichis cheap in point of manufacture and easy of operation.

I attach importance to the plates K, having spiral webs J, arranged at each corner of the table with webs inward, as they produce but a minimum of friction and wearingsurface upon the table-top when being passed in or out of the chambers.

I am aware that tables have heretofore been supplied with flexible tops rigidly fastened at one end and sliding into a box or winding around a shaft or drum at the opposite end, and I therefore do not claim either of these constructions. In my device the flexible top is. preferably fastened at its center to the table, and its ends slide into spirally-formed chambers placed at each end of the table. By this 6 5 construction the ends of the top slide into two boxes, and render it unnecessary to make either box of large or prominent size.

What I claim as my invention'is 1. The combination, in an extension-table, 7 of three supporting-sections, on one of which rests the central portion of a flexible top formed of slats whose ends run in spirally-formed guides J, attached to and forming part of the end supports, substantially as and for the purpose specified.

2. In an extension-table made in sections and having a flexible top, as described, and in combination with said sections and top, the side plates, K, fastened one at each side of the outer sections of the table, said plates being provided with internal spiral webs, J, forming guides for receiving the edges of the flexible top, substantially as specified.
